Used primarily as a fluorinating agent in organic synthesis, enabling the introduction of fluorine atoms into complex molecules. It is effective in reactions requiring strong electrophilic fluorination due to its high reactivity. Commonly employed in the preparation of fluorinated pharmaceuticals and agrochemicals where selective fluorination enhances biological activity and metabolic stability. Also utilized in materials science for modifying surface properties of polymers and semiconductors through fluorination. Its ability to act as a source of "naked" fluoride ions makes it valuable in catalysis and ionic liquid systems. Requires careful handling due to moisture sensitivity and strong oxidizing nature.
